Heat and Thermodynamics: Gas laws

1. A 24 liter tank is stored in a 15 degree C room. Its gauge reads 280 psi. A 50 liter tank is stored in a 34 degree C room. Its gauge reads 425 psi. The two tanks are then joined by a piece of tubing, the combination being placed in a 0 degree C cooler. However, in the connection process 8 percent of the total gas is lost. What will either pressure gauge read one day later?

2. A certain person is breathing at a normal rate, the power associated with this breathing being 100 mW. After a short period of hard exercise, the volume of air being inhaled is doubled. As a result, the power of breathing grows to 800 mW. What is occurring as a result of this increased breathing volume. Justify your answers.

Solution Summary

1. Two gas storage tanks at different pressure (psi) and temperature are connected, final pressure is calculated.
2. Power associated with breathing is increased.
